Something odd going on, may need to do a packet capture from another device and see what its doing.
the customized test worked ok using a WU ip address, but not the normal hostname used, as per their documentation, which i can only assume is also used in the wu settings of the gw1000.
running netcat on a pc listening on port 80, can see the url format sent from the gw1000
note:did the dns lookup on the wrong window, currently using cloudflare 1.1.1.1 , may try change it to another one and see if it starts working.
